Sounds reasonable.  Let’s wait for a green light from Ricardo.

I investigated and fixed it yesterday:

  
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=4bd70904c7f555a953808a9a4f892f462ffd352f

The thing is that there’s a separate finalization thread in Guile, which
takes care of finalizing dead objects.  For file ports, finalization
means closing the underlying file descriptor.  As it turns out,
‘close-port’ in Guile 2.0 would ignore EBADF errors, whereas
‘close-port’ in 2.2 reports them, hence the error.

The fix is to take extra care to close ports and not just the underlying
file descriptors.

I compared the source of eudev and systemd, and indeed, like Maxim
wrote, the issue is that eudev does not support a “uaccess” built-in
tag.  So I pushed a fix that simply comments out that line:

  
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=f8446df663fecb5aa34e5c6dfa477544d3271d1e

There’s still room for improvement, but the console output is less messy
now.  :-)

Thanks,
Ludo’.
